Abstract
La2Ti2O7:Pr powder was prepared by a solid-state reaction method. Photoluminescence due to f-f transitions of Pr3+was induced by band-gap excitation of La2Ti2O7. La2Ti2O7:Pr thin film was prepared by sol-gel and spin-coating methods. The thin film showed visible electroluminescence due to f-f transition of Pr3+by applying ac voltages.
